Having problems with your 1990 Ford Bronco ?

When i push on the brake hard it stays. but when i push on it to slow down the peddle goes all the way to the floor and does not stop. there is no air in the lines. but when i push on the brake there is bubbles coming up in the master cylinder where the brake fluid is stored. what is the problem and how do i fix it?
